The Hubble Space Telescope orbits the Earth at an approximate altitude of 612 km. Its mass is 11,100 kg and the mass of the Eart

h is 5.97×1024 kg. The Earth's average radius is 6.38×106 m. What is the magnitude of the gravitational force that the Earth exerts on the Hubble?

Answer:

magnitude of the gravitational force is 9.04 × 10^{4} N

Explanation:

given data

altitude = A = 612 km = 612000 m

mass M = 11,100 kg

mass of the Earth m = 5.97 × 10^{24} kg

Earth average radius = 6.38 × 10^{6}  m

to find out

magnitude of the gravitational force

solution

first we get here distance from space to centre of earth that is

distance = altitude + earth radius

distance = 612000  +  6.38 × 10^{6}  m

distance = 6.99 × 10^{6}  m  

so now we get here  magnitude of the gravitational force that is express as

magnitude of the gravitational force F = \frac{G*M*m}{distance^2}   ...........1

here G is gravitational constant  that is 6.67 × 10^{-11} Nm² /kg and M is mass of space and m is mass of earth

put here all value we get

F = \frac{G*M*m}{distance^2}

F = \frac{6.67*10^{-11}*5.97*10^{24}*11100}{(6.99*10^{6})^2}

F = 9.04 × 10^{4} N

so magnitude of the gravitational force is 9.04 × 10^{4} N

Assoli18 [71]

Answer:

4

Explanation:

The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .

yuradex [85]

Answer:

2\Omega

Explanation:

(Assuming the cell in the circuit has 0 internal resistance)

Ohm's Law is given as:

V=IR

Voltage is Current multiplied by Resistance.

We can rearrange this formula to give us:

R=\frac{V}{I}

Now we can plug in our values

R=\frac{6}{3}=2\Omega
